The X-Tension sleeve slips over the body of the extended mag to create an extended grip surface when the magazine is inserted into the pistol. Problems with Extended Mag & Grip SleeveĪs I previously stated, the pistol comes with two magazines: one flush fitting and the second is an extended magazine with an X-Tension grip sleeve. For improved low-light shooting, I recommend going with one of the aftermarket night sights for the XD-S line I talk about here. The significant downside to the fiber optic front (and the 2-dot rear) is that it doesn’t provide as good an aiming reference in low light as it does in bright. When you extend the pistol to a shooting position, the sight is very easy to see and quickly focus on. Speaking of sights, the red fiber optic front sight on the XD-S 4.0 really jumps out at you. At 25 yards, I was able to keep rounds in the high center mass area of a target without a problem. I think the longer barrel and sight radius really shine here. My second question is can I put well-aimed rounds on target at longer distances? Again, I could do so with the XD-S 4.0. At seven yards, I could easily put any number of rounds into the center mass area of a target as quickly as I could pull the trigger. The first is can I rapidly place multiple rounds on target quickly at close ranges, and the answer was yes. The aggressive texture on the grip frame helped me hold onto the gun with sweaty hands (welcome to Florida,) but was not uncomfortable after shooting hundreds of rounds.įor me, I generally have two questions. The extra barrel length and slide mass likely helped absorb some of the recoil, but even with the short grip, I thought the recoil was pretty easy – even with +P+ loads. All measurements are an average of five shots. Performance measured with a Competition Electronics ProChrono Digital Chronograph at an approximate distance of 15? from the muzzle of the pistol. I have not chronographed every load through the 4.0, but I have measured the performance of several rounds that are representative of my testing. I experienced no malfunctions with any of the ammo. I’ve shot more than 10 different kinds of ammo through the gun – a lot of 115 grain ball from Federal, Remington and Winchester, but also +P and +P+ hollowpoint loads. I attached several lights to this pistol during my review process. That’s not an issue with the XD-S 4.0″ pistol. This allows you to add a white light or laser if you are so inclined.Īnother company ran into an issue with its third iteration of pistols that – as the story goes – had reliability problems when certain kinds of ammo were used with a light mounted to its accessory rail. Springfield Armory designed the gun with an accessory rail under the barrel. Here are the factory specs on the the Springfield XD-S 4.0: Caliberīlack or matte stainless slide, black polymer Springfield Armory XD-S 4.0 9mm Specifications I suspected it would be infinitely better than the so-called New York trigger used on some Glock pistols. Of course, getting it on the range would prove whether I really liked it or not. However, it did not feel so heavy that I was turned off by it. This is a little heavier than many other striker-fired pistols, and it did feel heavier. Trigger weight measured 8 lb, 5 oz using a digital Lyman trigger pull gauge. Included in the case is the gun, a 7 round magazine, a 9 round magazine with an X-Tension grip sleeve, a polymer holster, a plastic double mag pouch, gunlock and paperwork. With a flush-fitting magazine in the Springfield XDS 4.0, I got the benefits of a thin gun with a short grip for concealment, but the improved velocity and accuracy of a duty-sized barrel.Īs it ships, the pistol comes in a hard plastic case and comes with a variety of extras. Also, the length of the grip can really affect how well the gun stays out of sight. The thickness of the gun, on the other hand, plays a huge role in concealability and comfort.

A full grip would not have allowed for this style of carry. With a Telor Tactical ankle holster, I was able to carry the XD-S 4.0″ concealed under a uniform pant leg.
